“Estrogen and testosterone are steroid hormones, and occur naturally in both sexes of humans, as well as in animals used for food. They help regulate sexual function and secondary sexual characteristics, in addition to nonsexual cellular functions. While estrogen plays many important beneficial roles in humans, it also naturally promotes proliferation of cells, and, at high levels, can increase risk of some cancers by encouraging cells to multiply more than they usually would. Hormone replacement therapy in postmenopausal women (specifically, taking only estrogen) has also been implicated in cancer growth. (2).” (Wilson, 2014).

“While soy does not contain estrogen, animal foods do. Many consumers are aware that animals used for meat and dairy are commonly supplemented with synthetic growth hormones, but what they don’t consider is that animal flesh and cow milk also contain their own naturally occurring estrogen— and this is true even of “grass-fed” and “organic” animals. Furthermore, meat, dairy and eggs all contain phytoestrogens; they are pervasive in our food, both plant and animal-derived, and you are not avoiding them entirely by avoiding soy” (Wilson, 2014).

“The inverse relationship between soy consumption and risk of developing premenopausal breast cancer has been clearly established. In other words, higher rates of soy intake are associated with lower rates of breast cancer. (3) However, large clinical trials have not yet been conducted regarding the effect of phytoestrogen consumption on tumor growth in established cancer patients. (4) To date, such studies have utilized small sample sizes, and the methods for obtaining data were highly variable. There have been ‘promising’ results from multiple animal models, demonstrating a reduction in tumor size with consumption of soy protein. Yet, aside from the immorality of artificially inducing cancer in unwilling participants, it is dangerous to compare laboratory animals to humans. We are not mice. Even within our species, there is tremendous variability in the metabolic processing of phytoestrogens and pharmacological agents, thus establishing the difficulty and complexity of this area of research. Instead, attention should be placed on the already available mass of epidemiological data which compares Asian cultures to those consuming a Western diet.” (Wilson, 2014)

“If indeed this were the case, there would be a lot of men in need of bras.” (Wilson, 2014)

Hun forsætter derefter med at forklare:

“In reality, clinical studies in men show that isoflavones do not affect testosterone levels or circulating estrogen levels. Even at levels of isoflavone exposure significantly higher than those of a typical Asian male consuming a soy rich diet, isoflavones have not been found to have feminizing effects. (6)” (Wilson, 2014)

Det gode ved soya

“Soy has long been recognized as a nutrient-dense food and as an excellent source of protein by respected dietitians and clinical nutritionists. (1) The soybean contains all of the essential amino acids, as well as an impressive list of micronutrients (vitamins and minerals). Micronutrients in rich supply in soy include: calcium, iron, magnesium, manganese, phosphorus, potassium, vitamins B1, B2, B3, B5, B6, B9, C and zinc. Fiber and omega-3 and 6 fatty acids are also present in soy. The composition of these nutrients varies among preparations, but is in the highest quantity in whole soy foods such as edamame (whole soy beans), soy milk, tofu and tempeh.” (Wilson, 2014).

“Soy myths and hysteria and the Weston A. Price Foundation (WAPF) are inseparable. Much of the fear-mongering around soy is a direct result of misinformation disseminated by the WAPF’s relentless anti-soy campaigns. The WAPF, registered as a nonprofit organization, is a multimillion dollar operation that lobbies for raw milk and grass-fed beef. Its members (often farmers) make financial contributions and in turn benefit from WAPF promotion.” (Wilson, 2014).

To give one example, there is a recent blog entry on the WAPF website from board member Kaayla Daniel, who attempted to interpret an article from the Journal of American Medical Association (JAMA) in a way that would promote the WAPF’s anti-soy agenda. On July 10 2013, JAMA published ‘Effect of Soy Protein Isolate Supplementation on Biochemical Recurrence of Prostate Cancer After Radical Prostatectomy’. (5) The study was well conducted (randomized and double-blind), and aimed to analyze whether or not soy intake would have any effect on patients being treated for advanced prostate cancer. Oncologists measured PSA (prostate specific antigen) in the blood at specific time intervals to assess response. It is not surprising that in patients with a lifetime consumption of foods high in animal fat and protein, pesticides, preservatives and antibiotics, and after a diagnosis of advanced cancer — that the biochemical markers were not affected by soy ingestion. The study could yield no solid conclusions about soy, except that with advanced prostate cancer, the consumption of soy will not reduce biochemical markers. Yet, the WAPF skewed data and selectively interpreted the study to support claims that further their anti-soy agenda.” (Wilson, 2014)

It’s also worth noting: Dr. Weston A Price (1870-1948) was a dentist, not a physician or a dietician. He studied teeth from primitive cultures and formulated dietary recommendations for modern society based on dental decay observations.” (Wilson, 2014)
